Metallic Minerals
Minerals that contain metallic elements and provide raw materials for metallurgical industries, such as iron ore, bauxite, and manganese.
Non-Metallic Minerals
Minerals that do not contain extractable metals, including limestone, mica, and gypsum, widely used in cement and fertilizer industries.
Conventional Energy Sources
Traditional, exhaustible sources of energy like coal, petroleum, natural gas, and electricity (thermal and hydro) that have been in use for a long time.
Non-Conventional Energy Sources
Renewable and eco-friendly sources of energy such as solar, wind, tidal, geothermal, and biomass energy.
Resource Conservation
The sustainable and judicious use of mineral and energy resources to meet present needs without compromising the ability of future generations.

Frequently Asked Questions
What are the major mineral resources found in Kerala?
Kerala is well known for beach sand minerals such as ilmenite, rutile, zircon, monazite, and sillimanite, along with extensive deposits of china clay (kaolin) and limestone.
Why is the shift towards non-conventional energy sources necessary?
Conventional sources like coal and petroleum are exhaustible, cause severe environmental pollution through greenhouse gas emissions, and are subject to price volatility. Non-conventional sources are renewable, clean, and sustainable.
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals and can be melted to extract new products (e.g., iron, copper), whereas non-metallic minerals do not yield metals and are used for their chemical or physical properties (e.g., limestone, dolomite).
